1 Claim. ((31. 126-42) The object of this invention is to provide an the metal of the tube, between adjacent slits, is exceedingly simple, inexpensive and efiicient depressed inwardly to form tongues 9 whereby some vice whereby the accidental or premature open resiliency is imparted to the tube at the slotted r ing of the valves of a gas range will be preventportion thereof. The tongues not only serve to ed. The cut-oil or regulating valves controlling prevent accidental displacement of the tube on 50 the flow of gas to the burners of a gas range are the gas pipe 2 but, by engagement with the bangenerally disposed in a line extending across the dies 4, serve to center said handles within the front of the range, and as the ranges are seldom tube as the latter is fitted over the valves 3 so of any appreciable height, the valves may be easthat the operator will know that all of said valves ily reached by young children and opened, or are securely closed. When the tube is to be em- 05 they may be accidentally opened by the reason ployed, one end thereof is engaged about the of the handles catching in the clothing of perhandle of the valve, at one end of the series of 'sons using or passing by the range. Considervalves, and the tube is then slid across the front able damage has resulted and lives have been lost of the range so as to successively engage and close by the unnoticed opening of the gas cocks and each and all of the valve handles. When the the consequent escape of gas from the burners. tongues are at the center of the tube, as shown in The present invention provides exceedingly sirn- Fig. l of the drawing, it will, of course, be necesple means whereby the accidental opening of the sary to adjust the tube longitudinally on the gas gas cocks will be prevented.
